Abstract: A camera using a film cartridge in which whether the film is exposed or unexposed can be distinguished by the phase of rotation of a shaft to rewinding a film, wherein said camera comprising: a film chamber to receive the film cartridge, a lid of the film chamber to capable of receiving the film cartridge in the film chamber when the lid is opened, a driving member which is connected with the shaft of the film cartridge and for driving the shaft, and a block member for blocking opening of the lid of the film chamber when the driving member is not the phase of rotation corresponding to the phase of rotation of the shaft in which the film is exposed.

Abstract: A film feeding apparatus of a camera using a film having two perforations in each frame. A perforation detecting lever has claws spaced at a predetermined distance apart from each other so that the distance therebetween is equal to the distance between the two perforations which are adjacent to each other across the boundary between frames. The perforation detecting lever engages the perforations and disengages therefrom in unison with an operation for feeding one frame to be performed after the proceeding frame is exposed to light. As a result, film feeding is allowed to proceed until both claws simultaneously engage two respective perforations in the film which occurs after the film has advanced one frame.

Abstract: A camera which includes a film cartridge whose spool is adapted to be set in different rotational positions with respect to a film cartridge main body between unused state and used state of the film cartridge, and a camera body having a film cartridge accommodating portion, and is arranged to show that the film cartridge is in the used state when the used film cartridge is inserted in the accommodating portion of the camera body.

Abstract: A camera system being comprised of a camera and an external device is disclosed. The external device is detachably mounted on the camera which memorizes a program or data necessary for executing a program therein.When the external device is mounted on the camera, they are connected electrically with each other and communicate therebetween in order to read a program or data memorized in the external device into a memory means provided in the camera. The camera is controlled according to the program designated by the external device.

Abstract: A camera system with an auto-focusing system includes a camera body and an interchangeable zoom lens. The interchangeable objective lens stores various data to be sent to the camera body for improving automatic focus adjustment, such as an information necessary to convert the detected defocus information into a movement of the driving power source to carry out the automatic focus adjustment. The driving power source in the camera body is controlled in response to the data from the interchangeable objective lens and the detected focus information, the driving power being transmitted to the interchangeable objective lens. The camera body is further capable of inhibiting the focus adjustment or focus indication in response to a data from the interchangeable objective lens under an unfavorable condition.

Abstract: A jaw bone anchored type head positioner for positioning the head of a subject which is employed in a cephalotomograph or temporomandibular joint radiograph using X rays or the like. A die patterned on an impression taken from the dentition of the subject is fixed to the positioner so that the head of the subject is fixed in position by means of the die.
